A tactile electromechanical switch 58 is provided in electrical and mechanical engagement with the circuit board 50. Mounting legs 60 extend from switch 58. The mounting legs 60 are configured to be inserted into and make electrical connections with through holes 54 of the circuit board 50. An activation button 62 extends from the tactile electromechanical switch 58 in a direction away from the circuit board 50.
During assembly of the sealed tailgate handle assembly 14, the exposed ends of the second ends of the cable 16 are positioned through the terminal receiving openings 46 such that the exposed ends of the second ends are placed in electrical engagement with the pads 56 of the circuit board 50. The exposed ends of the second ends of the cable 16 are soldered or welded to the pads 56 to maintain the exposed ends of the second ends of the cable 16 in electrical engagement with the pads 56. The seals 22 cooperate with the terminal receiving projections 44 to provide a seal therebetween.
With the exposed ends of the second ends of the cable 50, the circuit board 50 and the tactile electromechanical switch 58 properly positioned in the housing 24, a resin material 64 is placed in the circuit board receiving area 26. The resin material 64 encompasses the circuit board 50, sealing the connection between the exposed ends of the second ends of the cable 16 and the circuit board 50 and sealing the connection between the circuit board 50 and the tactile electromechanical switch 58.
A resilient member or spring 66 is positioned around the periphery of the tactile electromechanical switch 58. The spring 66 rests on the resin material 64.
As best shown in FIG. 5, an inner cover 68 has a curved or non-linear upper wall 70. Sidewalls 72 and end walls 74 extend from the upper wall 70. The sidewalls 72 and the end walls 74 are essentially perpendicular to the upper wall 70. The sidewalls 72 are positioned in slots 76 between the interior wall 34 of the circuit board receiving area 26 and the sidewalls 36 of the housing 24. Similarly, the end walls 74 are also retained in slots 78 in the housing 24. The sidewalls 72, the end walls 74 and the slots 76, 78 are dimensioned to allow the sidewalls 72, the end walls 74 and the inner cover 68 to move relative to the housing 24, the circuit board 50 and the tactile electromechanical switch 58 in a direction which is essentially perpendicular to the bottom wall 30 of the housing 24.
Latch receiving openings 80 are provided on the sidewalls 72 of the inner cover 68. The latch receiving openings 80 have latch engaging surfaces 82 which are configured to engage the cover latching projections 42. The latch receiving openings 80 are configured to receive the cover latching projections 42 therein.
The inner cover 68 has a switch receiving recess 84 provided between the sidewalls 72 and the end walls 74 which is dimensioned to receive the tactile electromechanical switch 58 and the spring 66 therein. Spring receiving recesses 86 extend from the switch receiving recess 84 and are dimensioned to receive and retain spring 66 in proper position relative to the inner cover 68.
Referring to FIGS. 6 and 7, as the inner cover 68 in inserted into the housing 24, the sidewalls 72 are movably positioned in slots 76, and the end walls 74 are movably positioned in the slots 78. The cover latching projections 42 are positioned in the latch receiving openings 80. In the initial or not compressed position, the spring 66 cooperates with the upper wall 70 of the inner cover 68 to bias the cover away from the tactile electromechanical switch 58. However, the cooperate of the cover latching projections 42 with the latch engaging surfaces 82 of the latch receiving openings 80 prevents the removal of the inner cover 68 from the housing 24 and retains the inner cover 68 in the initial or not compressed position.
As best shown in FIG. 6, an outer cover 88 has a deformably curved or non-linear upper wall 90. Sidewalls 92 and end walls 94 extend from the upper wall 90. The sidewalls 92 and the end walls 94 are essentially perpendicular to the upper wall 90. As best shown in FIGS. 7 through 9, the sidewalls 92 and end walls 94 have housing retaining slots 96 provided in housing retaining members 98. The outer cover 88 is made from material which is waterproof and which is not rigid, such as, but not limited to, rubber. The non-rigid flexible material allows the housing retaining members 98 and the retaining slots 96 to be mounted on and conform to the upper surface 40 of the housing 24 to provide a seal between the outer cover 88 and the housing 24, thereby preventing moisture or other contaminants from entering the housing.
As shown in FIGS. 7 and 8, with the outer cover 88 properly inserted onto the housing 24, the outer cover 88 and the inner cover 68 are retained in the initial or not compressed position. Upon an application of a force, as shown in FIG. 9, the upper wall 90 of the outer cover 88 is deformed, causing the inner cover to move from the initial or not compressed position, shown in FIGS. 7 and 8, to the second or compressed position, shown in FIG. 9. As this occurs, the applied force causes the spring 66 to compress, allowing the inner cover 68 to move toward and engage the activation button 62 of the tactile electromechanical switch 58. Continued movement of the outer cover 88 and inner cover 68 toward the bottom wall 30 of the housing 24 causes the tactile electromechanical switch 58 to complete an electrical circuit path on the circuit board 50, allowing the tactile electromechanical switch 58 to send a signal via the circuit board 50 and cable 16 to the tailgate release assembly 12 to release the tailgate.
After the pressure applied to the outer cover 88 is released, the spring returns toward the unstressed position shown in FIG. 7, thereby forcing the inner cover 68 to the initial or not compressed position and moving the inner cover 68 from engagement with the activation button 62 of the tactile electromechanical switch 58.
The present invention, as illustrated in the embodiment shown, provides for a compact sealed tailgate handle which prevents moisture, dirt and other contaminants from entering the sealed tailgate handle, thereby preventing failure of the sealed tailgate handle.
